ATTACHMENT FDR PRINTING-PRESSES.

Specification of Letters Patent.

Application filed March 9, 1909.

To all about it may concern:

Be it known that I, HUGH E. Simon, a citizen of the United States,residing at Austin, in the county of Mower and State of Minnesota, haveinvented certain new and useful Improvements in Attachments forPrinting-Presses, of which the following is a specification.

The invention relates to an improvement in printing presses, being moreparticularly directed to a bed-lock for ink table distribution presses,in the use of which the press bed of a cylinder printing press may bedivided to provide for properly locking the form in position withoutregard to the size of the latter.

In its essential characteristic the present invention includes a dividerwhich, together with fixed parts of the bed proper, is so formed that itmay be locked in any desired position longitudinally of the bed toprovide a transverse division, whereby in effect the longitudinaldimensions of the bed may be reduced in approximate accordance with thesimilar dimensions of the particular form to be used.

As an auxiliary feature the divider proper together with the frontlocking bar of the bed is formed to permit the arrangement oflongitudinally disposed dividing bars, so that the form-receiving spacein advance of the divider may be further adjusted as to its transversedimension in more or less accordance with the width of the form to beused.

The invention will be described in the following specification,reference being had particularly to the accompanying drawings, in whichFigure 1 is a plan view of a type bed and ink distribution tableillustrating my improvement. Fig. 2 is a vertical longitudinal sectionof the same on the line E2-2 of Fig. 1. Fig. 3 is a perspective of thedivider. Fig. 4; is a fragmentary perspective illustrating theconnection between the side bars and the locking bar.

Referring particularly to the accompanying drawings the improved typebed is shown as including side bars or bearers 1, which at their rearends are joined to the usual ink table 2. At their forward ends thebearers 1 are formed on their relatively inner or adjacent edges withlongitudinally extending grooves 3, designed to receive end tenons 4projecting from a front locking bar 5 of the bed. Clamps 6 ofappropriate form are arranged to engage the relatively forward edge ofthe locking bar to prevent the independ ent forward movement of thelatter, as is usual in beds of this type.

In the use of forms of different sizes with the type bed it is of courseessential that the form have a certain and definite printing position,generally near the front end of the bed. If the form is of materiallyless size than the bed it is necessary to fill in the remaining space,and this is ordinarily done by the use of furniture. ltn practice it isfound extremely diliicult to pack the bed with the furniture so as toprevent the latter from jumping up in the printing operation,

and this is particularly true where the form is only half or less thanhalf the size of the bed. The present invention is designed to avoid theobjections incident to the use of the furniture as above noted, by theprevisionof a divider which may be locked in any desired positionlongitudinally of the bearers so as to reduce the length of the bed inap proximate correspondence with the length of the form.

The divider comprises a metallic body 7 including a bearing bar 8 havingrearwardly extending guide arms 9 projecting from the ends of the bar, acurved brace bar 10 connected by webs 11 to the bar 8 being arranged onthe rear side of the latter for in creasii'ig the strength of thedivider.

In connection with the divider I contemplate the use of any desiredmeans for looking the same in appropriate positions length wise thebearers, preferring, however, for simplicity and ease of operation thefollowing construction for such purpose. The relatively inner edges ofeach of the bearers is formed with a series of longitudinally alinedholes 12 arranged at any desired intervals throughout the length of thebearers. Each hole of one bearer has a corresponding hole in the otherbearer in alinement therewith transverse the bed, and the guide arms 9of the divider are provided with pins 13, spring pressed in the outwarddirection by springs 14:, and adapted to seat in any of the openings 12.As thus arranged it will be evident that the divider may, by the simplemanipulation of the pins 13, be locked in any position longitudinally ofthe bed, whereby to reduce the length of the bed and in effect form anew bed for the reception of the form which has the forward looking barfor its front edge and the divider, or hearing bar 8 thereof, for itsrear edge.

As the space of the bed in front of the divider is the form-receivingspace, and as it frequently happens that the form to be used is ofmaterially less width than the width of the bed or two different formsmay be running at the same time, provision must be made for dividing theform-receiving space of the bed longitudinally. To this endthe bearingbar 8 of the divider and the proximate or inner edge of the locking bar5 are formed with notches or depressions 15, arranged in longitudinallyalined pairs, and adopted to receive dividing bars 16. These bars will,therefore, serve to divide the formreceiving space in advance of thedivider proper longitudinally of the bed thereby reducing the width ofsaid space. It is, of course, to be understood that the notches 15 maybe in any desired number and the divider bar 16 in appropriate lengthsto form any required division of the form-receiving space. The dividerbars in connection with the divider proper will permit the independentlocking of different forms in the bed, an advantage readily appreciatedby pressmen.

The invention provides for the ready and convenient adjustment of thelongitudinal and transverse dimension of the press bed in approximateaccordance with the similar dimensions of the form, whereby the lattermay be quickly and securely locked in position with the minimum offurniture, and the liability of displacement of the form or otherfurniture entirely avoided.

Having thus described the invention what is claimed as new, is

1. The combination with a type bed in eluding side bars formed on theirinner edges with a series of openings, and a looking bar removablyengaging the side bars, of a divider including a bearing bar having amaximum length equal to the distance between the side bars, and guidearms projecting from the ends of the bearing bar in a direction awayfrom the form engaging face of said bar, the bar and arms being of aheight equal to the similar dimensions of the side bars with the guidearms bearing throughout their lengths on the inner surfaces of the sidebars, and means carried by the guide arms to engage the openings in sidebars whereby to secure the divider. in place, the form engaging face ofthe hearing bar and the proximate face of the looking bar being formedwith notches, and a dividing bar adapted to seat in alined notches, ofthe locking bar and bearing bar.

2. An article of manufacture, an integral divider bar for printing beds,comprising a bearing bar of the maximum length equal to the fullinterior width of the bed, arms projecting from the respective ends ofthe bar with their outer surfaces in alinement with the ends of the bar,spring actuated locking devices mounted in. the arms, a curved brace barhaving its ends coincident with the bearing bar and its central portionspaced the maximum distance from the proximate center of said bar, andwebs connecting the brace bar and bearing.

3. The combination with a type bed including side bars formed on theirinner edges with a series of openings and at their ends with a guide,and a locking bar cooperating with the guides in the ends of the sidebars, and removably mounted, of a divider including a bearing bar havinga maximum length equal to the distance between the side bars, and guidearms projecting from the ends of the bearing bar in a. direction awayfrom the form engaging face of said bar, the bar and arms being of aheight equal to the similar dimensions of the side bars with the guidearms bearing throughout their lengths on the inner surfaces of the sidebars, and spring actuated means carried by the guide arms to engage theopenings in the side bars whereby to secure the divider in place, theform engaging face of the bearing bar and the proximate face of thelocking bar being formed with notches, a dividing bar adapted to seat inalined notches of the locking bar and bearing bar and clamps carried bythe locking bar.

In testimony whereof I aliix my signature in presence of two witnesses.
